Hi Guys, remember me? I'd first of all like to thank everyone who has taken the time to reply, Im delighted with the feedback. Ive discovered & installed a lot of really useful programs thanks to the recommendations made here. Ram Idle, came & went Crap Cleaner JV16 Power tools Perfect Disk These got a lot of junk off of my system. After all these my system is definitely a bit better, but still not as quick as I would like. My bench mark test (and this is totally untechnical) is when I click Start>All Programs,it can take what seems like an eternity for the list to open. I can live with it the way it is now, but still feel it should be better. Having said that I have'nt yet carried out some of the more technical recommendations posted here. In answer to one or two other points, the hard disc is 7200rpm, and as far as cooling goes, there is plenty of air flowing around the pc (BTW, is there a way to check the processor temperature?) Thanks again
